The "Dancing With The Stars" contestant spoke to Access Hollywood about the physical challenges required to be a top contender in the hit ABC reality competition, which included a rigorous rehearsal routine.

"Oh my God -- I'm covered in [bruises]," she added.

Vanderpump, who stars on Bravo's "Real Housewives of Beverly Hills" as well as "Vanderpump Rules," expressed trepidation about performing the Jive, a face-paced dance similar to swing, for the upcoming episode. But the reality star remained optimistic.

"It's kind of intimidating, but you know what? If you land on your [expletive], or you screw up, that's the journey isn't it?"
